Before You Start

+

This section describes version compatibility and important notes about Object Storage Service (OBS) SDK for Java.

+

Compatibility

  • Recommended JDK versions: JDK 8 or later
  • Third-party dependencies: This version is not completely compatible with earlier versions (2.1.x). OkHttp 3 should be used to replace HttpClient4.x.
  • Namespace: This version is compatible with earlier versions (2.1.x). All external APIs are contained in the com.obs.services, com.obs.services.model, and com.obs.services.exception packages.
  • API functions: This version is compatible with earlier versions (2.1.x).
  • The earlier 2.X versions are no longer maintained. You are advised to upgrade them to the latest version as soon as possible.
+
+

Important Notes

  • Make sure that you are familiar with OBS basic concepts in Help Center, such as buckets, objects, regions, and access keys (AKs/SKs).
  • You can learn about how to call an API through the OBS SDK for Java by referring to Using an OBS Client.
  • After an API is called using an instance of ObsClient, if no exception is thrown, the return value is valid. If an exception is thrown, the operation fails. For details about errors, see SDK Exceptions.
  • After an API is successfully called using an instance of ObsClient, a class or sub-class instance of HeaderResponse that contains response headers will be returned.
  • Some features are available only in some regions. If an API call returns the 405 HTTP status code, check whether the region supports this feature.

Preparations

+

Before using OBS SDK for Java to access OBS, you need to prepare the service and development environments. To prepare the service environment, you will need an account and access keys. Both of them are necessary for interaction between OBS SDK and OBS. To ensure successful SDK installation and SDK-based code development and running, you should also set up a local development environment, for example, installing dependencies and development tools.

+

Preparing Access Keys

Access keys consist of two parts: an access key ID (AK) and a secret access key (SK). OBS uses access keys to sign requests to make sure that only authorized accounts can access specified OBS resources. Programmatic access must be enabled for an IAM user before the IAM user can get access keys. Access keys are explained as follows:

+
  • One AK maps to only one user but one user can have multiple AKs. OBS authenticates users by their AKs.
  • An SK is required for accessing OBS. Authentication information is generated based on the SK and request headers. AKs and SKs are in one-to-one match.
+

Access keys are classified into permanent access keys (AK/SK) and temporary access keys (AK/SK and security token). Each user can create at most two permanent access keys. Temporary access keys must be used within a given validity period. Once expired, they must be requested again. For security purposes, you are advised to use temporary access keys to access OBS. If you want to use permanent access keys, periodically update them. The following describes how to obtain two types of access keys.

+
  • To get permanent access keys, do as follows:
    1. Log in to the management console.
    2. In the upper right corner, hover over the username and choose My Credentials.
    3. On the My Credentials page, click Access Keys in the navigation pane.
    4. On the Access Keys page, click Create Access Key.
    5. In the displayed dialog box, enter the login password and verification code.
      • If you have not bound an email address or a mobile number yet, only the login password is required.
      • If you have bound both an email address and a mobile number, you can use either of them for verification.
      +
      +
    6. Click OK.
    7. Click Download. The access key file is automatically saved to your browser's default download path.
    8. Open the downloaded credentials.csv file to obtain the access keys (AK and SK).
      • Each user can create a maximum of two valid access key pairs.
      • Keep AKs and SKs properly to prevent information leakage. If you click Cancel in the download dialog box, the access keys will not be downloaded and cannot be downloaded later. You can create a new AK/SK pair if needed.
      +
      +
    +
  • To get temporary access keys, refer to the following:

    Temporary access keys are issued by the system and are only valid for 15 minutes to 24 hours. Once expired, they must be requested again. They follow the principle of least privilege. When a temporary AK/SK pair is used for authentication, a security token must be used at the same time.

Description

+

Creating and Configuring an OBS Client

+

Creating an OBS client

+

Yes

+

OBS clients offer a series of APIs for you to use OBS SDK for Java to interact with OBS. Before sending a request to OBS, you need to create and initialize an OBS client (an ObsClient instance).

+

Configuring access credentials

+

Yes

+

For security purposes, you need to configure access credentials for the client so that the server can verify the validity of requests.

+

Configuring the endpoint and other parameters

+

Yes for the endpoint; No for other parameters

+
  • To quickly create and retrieve your resources, you need to configure an endpoint for the client so that the server can know where to create or retrieve resources.
  • You can configure other parameters for the client based on your needs.
+

Configuring SDK Logging

+

Configuring a log level

+

No

+

OBS SDK for Java offers logging based on the open-source library of Apache Log4j 2. The Log4j 2 framework classifies log files into different levels based on their priorities. You can specify a log level to customize the log storage scope.

+

By default, OBS SDK for Java saves log files of the WARN and higher levels to local directories.

+

Configuring a storage path for log files

+

No

+

Configure a local path to store logs.

+

Scenarios

This section describes how to create and configure an OBS client. If you already have a client, skip this section and obtain the API details by referring to API Overview.

+
+

Prerequisites

Ensure you have completed the following preparations:

+
  1. Select a proper SDK version by referring to Before You Start.
  2. Prepare the service and development environments by referring to Preparations.
  3. Download and install the OBS SDK for Java by referring to SDK Download and Installation.
+
+

Important Notes

  • Make sure to configure the client at the time you create it. After the client is created, you will not be able to configure it.
  • If you use a temporary AK/SK pair, you can call ObsClient.refresh("yourAccessKey", "yourSecretKey", "yourSecurityToken") to refresh to keep the pair valid, without the need to create a new ObsClient instance.
  • You are advised to create an ObsClient instance at the initialization and use it for the whole project. Creating multiple clients affects high-concurrency performance.
  • ObsClient is thread-safe and can be used in concurrency scenarios.
  • If a client is closed by calling ObsClient.close, it cannot be used again. To ensure the whole project uses only one client, you are advised not to proactively close the client.
+
+

Sample Code

+

Client

+

Client that does not transparently transmit access credentials

+

If you want to configure access credentials only once and use them for all API calls, use ObsClient.

+

ObsClient

+

Client that transparently transmits access credentials

+

If you need to configure access credentials for each API call, use SecretFlexibleObsClient, which is inherited from ObsClient.

+

SecretFlexibleObsClient

+

Access credentials

+

Passing access credentials as parameters

+

Create an ObsClient instance and pass access credentials as parameters.

+		 +

Obtaining access credentials from environment variables

+

Create an ObsClient instance and use EnvironmentVariableObsCredentialsProvider to obtain access credentials from environment variables.

+

+

EnvironmentVariableObsCredentialsProvider

+

Obtaining access credentials from an agency in ECS scenarios

+

Create an ObsClient instance and use EcsObsCredentialsProvider to automatically obtain temporary access credentials from the ECS. The access credentials are periodically updated automatically.

+
NOTICE:
  1. To use EcsObsCredentialsProvider, ensure that the application runs on an ECS that has an IAM agency with OBS permissions.
  2. Ensure that the server and the environment where the application is deployed have the same UTC time, or temporary access keys may fail to be updated in a timely manner.
+
+

EcsObsCredentialsProvider

+

Using a chain to search for access credentials

+

You can use this method to search for access keys in a chain in a predefined sequence. The first pair of access keys obtained is used to create an ObsClient instance.

+

By default, environment variables are checked first and then the ECS agencies are checked to obtain access credentials. You cannot customize the search method or sequence.

+

OBSCredentialsProviderChain

+

Other configurations

+

Configuring only the endpoint

+

Other than access credentials, only the endpoint is configured.

+

Configuring Only the Endpoint

+

Configuring the endpoint and other parameters

+

In addition to the endpoint, you need to configure the HTTP proxy, Socket timeout, and other parameters. You can use the ObsConfiguration class to configure the ObsClient instance. For details about the supported parameters, see Table 2.

+

ObsConfiguration

+
+

Configuring SDK Logging

+

OBS SDK for Java offers logging based on the open-source Apache Log4j 2 library. By default, the SDK stores WARN log files to the directory specified by the JDK system variable user.dir. You can modify the log configuration file based on your needs.

+

Procedure

  1. Obtain the file log4j2.xml from the OBS SDK for Java package.
  2. Modify the log level and storage path in the file as required.
  3. Save the file to the classpath root directory, or call Log4j2Configurator.setLogConfig to specify the storage path of the file.
+
+
  • For details about SDK logging, see Log Analysis.
  • You can modify the log4j2.xml file to configure access permissions for log files.

+    e.printStackTrace(System.out);
+}
+
    +

    +
    +

  4. If an exception occurs when an ObsClient API is called, obtain the HTTP status code and OBS server-side error code from ObsException or log file, and compare them to locate the exception cause.
  5. If the exception cause cannot be found in step 4, obtain the request ID returned by the OBS server from ObsException or log file and contact the OBS server O&M team to locate the cause.
  6. If the request ID is unable to be obtained, collect the stack information of ObsException and contact the OBS client O&M team to locate the cause.

Other Notable Issues

+

SignatureDoesNotMatch

1
+2
HTTP Code: 403
+Error Code: SignatureDoesNotMatch
+
+
+

Possible causes are as follows:

+
  1. The SK input into ObsClient initialization is incorrect. Solution: Make sure that the SK is correct.
  2. This problem is caused by a bug in the OBS Java SDK of an earlier version. Solution: Upgrade the SDK to the latest version.
  3. OBS Java SDK 2.1.x versions are incompatible with the dependent library Apache HttpClient. Solution: Use httpcore-4.4.4 and httpclient-4.5.3.
+
+

MethodNotAllowed

1
+2
HTTP Code: 405
+Error Code: MethodNotAllowed
+
+
+
+

This error occurs because a feature on which the ObsClient API depends has not been rolled out on the requested OBS server. Contact the OBS O&M team for further confirmation.

+

BucketAlreadyOwnedByYou

1
+2
HTTP Code: 409
+Error Code: BucketAlreadyOwnedByYou
+
+
+
+

In OBS, a bucket name must be globally unique. Solution: If this error occurs when the ObsClient.createBucket is called, check whether the bucket exists. You can use either of the following methods to check whether a bucket exists:

+

Method 1 (recommended): Call ObsClient.listBuckets to query the list of all buckets that you own and check whether the bucket exists.

+

Method 2: Call ObsClient.headBucket to check whether the bucket exists.

+

ObsClient.headBucket can query only buckets in the current region, while ObsClient.listBuckets can query buckets in all regions.

+
+

BucketAlreadyExists

1
+2
HTTP Code: 409
+Error Code: BucketAlreadyExists
+
+
+
+

In OBS, a bucket name must be globally unique. Solution: If this error occurs when ObsClient.createBucket is called, it indicates that the bucket has been created by another user. Use a different bucket name and try again.

+
+
+

Possible causes are as follows:

+
  1. The endpoint input during ObsClient initialization is incorrect. Solution: Make sure that the endpoint is correct.
  2. The network between the OBS client and OBS server is abnormal. Solution: Check the health status of the network.
  3. The OBS domain name resolved by DNS is inaccessible. Solution: Contact the OBS O&M team.

  1. The network latency between the OBS client and OBS server is too long. Solution: Check the health status of the network.
  2. The network between the OBS client and OBS server is abnormal. Solution: Check the health status of the network.
+
+

Abnormal Returned Value -1

1
HTTP Code: -1
+
+
+
+

Possible causes are as follows:

+
  1. The OBS Java SDK of an earlier version is used and a connection timeout or read/write timeout occurs. Solution: See the solutions for connection timeout and read/write timeout.
  2. This is a bug in earlier versions of OBS Java SDK. Solution: Use .
  3. The server returns an exception. Solution: Obtain the request ID returned by OBS server from the log and contact the OBS O&M team.
+

Unable to Obtain Error Codes from ObsException

Possible causes are as follows:

+
  1. An error is reported when ObsClient.getBucketMetadata or ObsClient.getObjectMetadata is called. In this scenario, the server does not return an error code because the request method used in the background is HEAD. Solution: Call ObsException.getResponseCode to obtain the HTTP status code to analyze the possible cause. For example, 403 indicates that the user does not have the access permission, and 404 indicates that the bucket or object does not exist. If the cause cannot be located, obtain the request ID returned by the OBS server from ObsException and contact the OBS O&M team.
  2. The endpoint passed during ObsClient initialization cannot correspond to a valid IP address of the OBS server after DNS resolution. Solution: Check whether the endpoint is correct. If the endpoint is correct, contact the OBS O&M team.

Creating a Bucket

+

Function

This API creates an OBS bucket. Buckets are containers for storing objects (files uploaded to OBS) in OBS.

+

When creating a bucket, you can also configure parameters such as the storage class, region, and access control list (ACL) as needed.

+
+

Restrictions

  • To create a bucket, you must have the obs:bucket:CreateBucket permission. IAM is recommended for granting permissions. For details, see .
  • A maximum of 100 buckets and parallel file systems in total can be created globally for an account. There is no limit on the number or size of objects stored in a bucket.
  • The created bucket name must be unique in OBS. If you repeatedly create buckets with the same name in the same region, an HTTP status code 200 will be returned. In other cases, creating a bucket with an existing bucket name will have an HTTP status code 409 returned, indicating that such a bucket already exists.
  • The name of a deleted bucket can be reused for another bucket or a parallel file system at least 30 minutes after the deletion.
+
+

Method

  • Method 1: Create a bucket with a specified name.

    createBucket(String bucketName)

    +
  • Method 2: Create a bucket with a specified name in a specified region.

    createBucket(String bucketName, String location)

    +
+
  • Method 3: Create a bucket with a specified name in a specified region.

    createBucket(ObsBucket bucket)

    +
+
  • Method 4: Create a bucket and configure access permissions, storage class, location, cluster type, bucket type (object bucket or parallel file system), enterprise project ID, and extension permissions for the bucket.

If this permission is granted on an object, anyone can read the content and metadata of the object.

+

AccessControlList.REST_CANNED_PUBLIC_READ_WRITE

+

Public read/write.

+

If this permission is granted on a bucket, anyone can read the object list, multipart uploads, and bucket metadata, and can upload or delete objects, initiate multipart uploads, upload parts, assemble parts, copy parts, and abort multipart upload tasks.

+

If this permission is granted on an object, anyone can read the content and metadata of the object.

+

AccessControlList.REST_CANNED_PUBLIC_READ_DELIVERED

+

Public read on a bucket as well as objects in the bucket.

+

If this permission is granted on a bucket, anyone can read the object list, multipart tasks, and bucket metadata, and can also read the content and metadata of the objects in the bucket.

Deleting a Bucket

+

Function

This API deletes an empty bucket. You can delete buckets you no longer use to free up space. The name of a deleted bucket can be reused for another bucket at least 30 minutes after the deletion.

+
+

Restrictions

  • Only empty buckets can be deleted. An empty bucket means that:
    • The bucket does not contain any object (including noncurrent versions and delete markers).
    • The bucket does not contain any fragments, which means that there are no multipart uploads that have not been completed in the bucket.
    +
  • To delete a bucket, you must be the bucket owner or have the required permission (obs:bucket:DeleteBucket in IAM or DeleteBucket in a bucket policy).
  • Only empty buckets (without objects and part fragments) can be deleted.
  • Bucket deletion is a non-idempotence operation and an error will be reported if the bucket you want to delete does not exist.
+
+

Setting a Bucket ACL

+

Function

Access control lists (ACLs) allow resource owners to grant other accounts the permissions to access resources. By default, only the resource owner has full control over resources when a bucket or object is created. That is, the bucket creator has full control over the bucket, and the object uploader has full control over the object. Other accounts do not have the permissions to access resources. If resource owners want to grant other accounts the read and write permissions on resources, they can use ACLs. ACLs grant permissions to accounts. After an account is granted permissions, both the account and its IAM users can access the resources.

+

+
+

You can configure a bucket ACL by referring to Method.

+

Restrictions

  • A bucket can have up to 100 ACL rules.
  • To configure an ACL for a bucket, you must be the bucket owner or have the required permission (obs:bucket:PutBucketAcl in IAM or PutBucketAcl in a bucket policy).
+
+

Method

  • Method 1: Set a pre-defined ACL when creating a bucket.
    obsBucket.setBucketName(exampleBucket);
+// Set the bucket ACL to private read and write.
+obsBucket.setAcl(AccessControlList.REST_CANNED_PRIVATE);
+// Create a bucket.
+obsClient.createBucket(obsBucket);
    +
  • Method 2: After the bucket is created, set a pre-defined ACL.
    // Set the bucket ACL to private read and write.
+obsClient.setBucketAcl(String exampleBucket, AccessControlList.REST_CANNED_PRIVATE);
    +
+
  • Method 3: After the bucket is created, set a user-defined ACL.
    // Set a user-defined ACL for the bucket.
+obsClient.setBucketAcl(String bucketName,AccessControlList acl);

Configuring a Bucket Policy

+

Function

OBS provides access control over buckets. You can use an access policy to define whether a user can perform certain operations on a specific bucket. OBS access control can be implemented using IAM permissions, bucket policies, and ACLs.

+

A bucket policy applies to both the bucket and objects therein. You can use a bucket policy to grant permissions for a bucket and objects therein to IAM users or other accounts. If you want IAM users to have different permissions for different buckets, you need to configure different bucket policies for those users.

+
+

Besides bucket ACLs, bucket owners can use bucket policies to centrally control access to buckets and objects in buckets.

+

You can call ObsClient.setBucketPolicy to configure a bucket policy.

+

Restrictions

  • Due to data caching, after a bucket policy is configured, it takes 5 minutes at most for the policy to take effect.
  • To configure a bucket policy, you must be the bucket owner or the bucket owner's IAM user with the required permission (obs:bucket:PutBucketPolicy in IAM or PutBucketPolicy in a bucket policy).
  • The latest policy configurations will overwrite the preceding configurations when you call the API for configuring a bucket policy. For example, if you have configured bucket policies A, B, C, and D and you want to add a new bucket policy E, you must add policy E to the file containing the existing four policies and then upload the file with all policies contained. Likewise, if you want to delete bucket policy D, you must remove it from the file containing policies A, B, C, and D, and then upload the file without policy D contained.
  • OBS returns 404 NoSuchBucketPolicy when you call this API in the following scenarios:
    • The specified bucket policy does not exist.
    • The standard policy of the specified bucket is set to Private and no advanced policies are configured.
    +
+
+

Method

obsClient.setBucketPolicy(String bucketName, String policy)

Configuring a Storage Quota

+

Function

A quota limits the maximum capacity allowed in a bucket. By default, there is no limit on the storage capacity of the entire OBS system or a single bucket, and any number of objects can be stored. You can set a storage quota to control the total size of objects that can be uploaded to the bucket. After the storage quota has been reached, object upload will fail.

+

A quota limit does not apply to the objects uploaded before the quota is configured. If the specified quota is already smaller than the total size of existing objects in the bucket, the existing objects in the bucket will not be deleted, but no more object can be uploaded to the bucket later. In this case, to upload new objects, you must delete some of the existing objects to make the used space below the quota limit.

+
+

Restrictions

  • A bucket quota must be a non-negative integer in bytes.
  • OBS does not provide an API for deleting bucket storage quotas. You can set the bucket storage quota to 0 to cancel the limit.
  • To configure a storage quota for a bucket, you must be the bucket owner or have the required permission (obs:bucket:PutBucketQuota in IAM or PutBucketQuota in a bucket policy).
+
+

Method

obsClient.setBucketQuota(String bucketName, BucketQuota bucketQuota)

Configuring a Storage Class for a Bucket

+

Function

This API configures a storage class for a bucket. If you do not specify a storage class when uploading or copying an object, or initiating a multipart upload, the object inherits the bucket's storage class.

+
+

The following table lists the three available storage classes.

+ +
+ + + + + + + + + +

Storage Class

+

Description

+

Value in OBS Java SDK

+

Standard

+

Features low access latency and high throughput and is used for storing massive, frequently accessed (multiple times a month) or small objects (< 1 MB) requiring quick response.

+

StorageClassEnum.STANDARD

+
+
+

Restrictions

  • To configure a storage class for a bucket, you must be the bucket owner or have the required permission (obs:PutBucketStoragePolicy in IAM or PutBucketStoragePolicy in a bucket policy).
  • The bucket storage class is independent from the storage classes of objects in the bucket. When uploading an object, if you do not specify a storage class for the object, the object will use the same storage class that the bucket uses. However, after the object is uploaded, its storage class will not change as that of the bucket changes. Likewise, the storage class of the bucket will also not change if the storage class of any objects therein changes.
+
+

Method

obsClient.setBucketStoragePolicy(String bucketName, BucketStoragePolicyConfiguration bucketStorage)

+
+

Obtaining a Bucket ACL

+

Function

Access control lists (ACLs) allow resource owners to grant other accounts the permissions to access resources. By default, only the resource owner has full control over resources when a bucket or object is created. That is, the bucket creator has full control over the bucket, and the object uploader has full control over the object. Other accounts do not have the permissions to access resources. If resource owners want to grant other accounts the read and write permissions on resources, they can use ACLs. ACLs grant permissions to accounts. After an account is granted permissions, both the account and its IAM users can access the resources.

+

+

This API returns the ACL of a bucket.

+
+

Restrictions

  • To obtain the ACL of a bucket, you must be the bucket owner or have the required permission (obs:bucket:GetBucketAcl in IAM or GetBucketAcl in a bucket policy).
+
+

Configuring an Inventory Rule

+

Function

This API configures an inventory rule for the bucket. With this API, object information in a bucket (source) is regularly listed and saved as CSV files. These files are then stored in a specified bucket (destination). In this manner, you can easily manage objects in a bucket. A source bucket can also be the destination bucket. A bucket inventory file contains the following object-related information: object versions, sizes, storage classes, tags, encryption statuses, and last modification time.

+

You can encrypt bucket inventory files using SSE-KMS.

+
+

Restrictions

  • To configure an inventory rule for a bucket, you must be the bucket owner or have the required permission (obs:bucket:PutBucketInventoryConfiguration in IAM or PutBucketInventoryConfiguration in a bucket policy).
  • Bucket versions
    • Bucket inventories can be generated only for OBS 3.0 buckets, but they can be stored in either OBS 3.0 or OBS 2.0.
    +
  • Number of bucket inventory rules
    • A bucket can have a maximum of 10 inventory rules.
    +
  • Source and destination buckets
    • The source bucket (for which a bucket inventory rule is configured) and the destination bucket (where the generated inventory files are stored) must belong to the same account.
    • The source bucket and the destination bucket must be in the same region.
    • Default encryption cannot be enabled for the destination bucket configured for storing inventory files.
    +
  • Functions
    • Inventory files must be in the CSV format.
    • OBS can generate inventory files for all objects in a bucket or a group of objects whose names begin with the same prefix.
    • If a bucket has multiple inventory rules, the filtering criteria in these rules must not overlap.
      • If a bucket already has an inventory rule for the entire bucket, new inventory rules that filter objects by prefixes cannot be created. If you need an inventory rule that covers only a subset of objects in the bucket, first delete the inventory rule configured for the entire bucket.
      • If an inventory rule that filters objects by a specified prefix already exists, you cannot create an inventory rule for the entire bucket. To create an inventory rule for the entire bucket, make sure that the bucket has no inventory rules that filter objects by specified prefixes.
      • If a bucket already has an inventory rule that filters objects by the object name prefix, such as ab, the filter of a new inventory rule cannot be any prefix that contains a, b, or ab. If you still need to create such rules, delete the inventory rule that uses the prefix ab first.
      +
    • Bucket inventory files only support SSE-KMS encryption.
    +
  • Permissions
    • Inventory files are uploaded to the destination bucket by an OBS system user. Therefore, you need to grant the system user the permission to write objects to the destination bucket.
    +
  • Others
    • The bucket inventory function is offered for free, but inventory files are billed for the storage they use.

Overview

+

In OBS, objects are basic data units that users can perform operations on. OBS Java SDK provides abundant APIs for object upload in the following methods:

+ +

The SDK supports the upload of objects whose size ranges from 0 KB to 5 GB. For streaming upload, appendable upload, and file-based upload, data to be uploaded cannot be larger than 5 GB. If the file is larger than 5 GB, multipart upload (where each part is smaller than 5 GB) is suitable. Browser-based upload allows files to be uploaded through a browser.

+

If you grant anonymous users the read permission for an object during the upload, anonymous users can access the object through a URL after the upload is complete. The object URL is in the format of https://bucket name.domain name/directory level/object name. If the object resides in the root directory of the bucket, its URL does not contain directory levels.

Uploading an Object - Streaming

+

Function

This API uploads a local file to OBS over the Internet. These files can be texts, images, videos, or any other type of files.

+

You can upload texts, images, videos, or any other types of files smaller than 5 GB. In a streaming upload, java.io.InputStream is used as the object data source. You can call ObsClient.putObject to upload data streams to OBS.

+
+

Restrictions

  • To upload an object, you must be the bucket owner or have the required permission (obs:object:PutObject in IAM or PutObject in a bucket policy).
  • The object size in a single upload ranges from 0 to 5 GB.
  • To upload files larger than 5 GB, refer to Multipart Upload.
  • To upload a local file, you are advised to use a file-based upload. For details, see Uploading an Object - File-Based.

+

Explanation:

+

HTTP status code.

+

Value range:

+

A status code is a group of digits that can be 2xx (indicating successes) or 4xx or 5xx (indicating errors). It indicates the status of a response.

+

Default value:

+

None

+

responseHeaders

+

Map<String, Object>

+

Explanation:

+

Response header list, composed of tuples. In a tuple, the String key indicates the name of the header, and the Object value indicates the value of the header.

+

Default value:

+

None

+

storageClass

+

StorageClassEnum

+

Explanation:

+

Object storage class. If the storage class is Standard, leave this parameter blank.

+

Value range:

+

See Table 21.

+

Default value:

+

None

+

versionId

+

String

+

Explanation:

+

Object version ID. If versioning is enabled for the bucket, the object version ID will be returned.

+

Value range:

+

The value must contain 32 characters.

+

Default value:

+

None

+

etag

+

String

+

Explanation:

+

ETag of an object, which is a Base64-encoded 128-bit MD5 digest. ETag is the unique identifier of the object content. It can be used to determine whether the object content is changed. For example, if the ETag is A when an object is uploaded and is B when the object is downloaded, the object content is changed. The ETag reflects changes only to the contents of the object, not its metadata. An object created by an upload or copy operation has a unique ETag.

+

Restrictions:

+

If an object is encrypted using server-side encryption, the ETag is not the MD5 value of the object.

+

Value range:

+

The value must contain 32 characters.

+

Default value:

+

None

+

objectKey

+

String

+

Explanation:

+

Object name. An object is uniquely identified by an object name in a bucket. An object name is a complete path that does not contain the bucket name.

+

Value range:

+

The value must contain 1 to 1,024 characters.

+

Default value:

+

None

+

bucketName

+

String

+

Explanation:

+

Bucket name.

+

Restrictions:

+
  • A bucket name must be unique across all accounts and regions.
  • A bucket name:
    • Must be 3 to 63 characters long and start with a digit or letter. Lowercase letters, digits, hyphens (-), and periods (.) are allowed.
    • Cannot be formatted as an IP address.
    • Cannot start or end with a hyphen (-) or period (.).
    • Cannot contain two consecutive periods (..), for example, my..bucket.
    • Cannot contain periods (.) and hyphens (-) adjacent to each other, for example, my-.bucket or my.-bucket.
    +
  • If you repeatedly create buckets of the same name in the same region, no error will be reported and the bucket attributes comply with those set in the first creation request.
+

Default value:

+

None

+

+

Public read.

+

If this permission is granted on a bucket, anyone can read the object list, multipart uploads, bucket metadata, and object versions in the bucket.

+

If this permission is granted on an object, anyone can read the content and metadata of the object.

+

AccessControlList.REST_CANNED_PUBLIC_READ_WRITE

+

Public read/write.

+

If this permission is granted on a bucket, anyone can read the object list, multipart uploads, and bucket metadata, and can upload or delete objects, initiate multipart uploads, upload parts, assemble parts, copy parts, and abort multipart upload tasks.

+

If this permission is granted on an object, anyone can read the content and metadata of the object.

+

AccessControlList.REST_CANNED_PUBLIC_READ_DELIVERED

+

Public read on a bucket as well as objects in the bucket.

+

If this permission is granted on a bucket, anyone can read the object list, multipart tasks, and bucket metadata, and can also read the content and metadata of the objects in the bucket.

+

This permission cannot be granted on objects.

+

AccessControlList.REST_CANNED_PUBLIC_READ_WRITE_DELIVERED

+

Public read/write on a bucket as well as objects in the bucket.

+

If this permission is granted on a bucket, anyone can read the object list, multipart uploads, and bucket metadata, and can upload or delete objects, initiate multipart upload tasks, upload parts, assemble parts, copy parts, and abort multipart uploads. They can also read the content and metadata of the objects in the bucket.

+

This permission cannot be granted on objects.

+

AccessControlList.REST_CANNED_BUCKET_OWNER_FULL_CONTROL

+

If this permission is granted on an object, only the bucket and object owners have the full control over the object.

+

By default, if you upload an object to a bucket owned by another user, the bucket owner does not have the permissions on your object. After you grant this permission to the bucket owner, the bucket owner can have full control over your object.

+

For example, if user A uploads object x to user B's bucket, user B does not have the control over object x. If user A sets bucket-owner-full-control for object x, user B then has the control over object x.

Creating a Folder

+

Function

This API creates a folder in an existing bucket to manage data in OBS.

+

OBS does not involve folders like in a file system. All elements in buckets are objects. To create a folder in OBS is essentially to create an object whose size is 0 and whose name ends with a slash (/). Such objects are no different from other objects (you can perform normal operations on them such as download and delete), except that they are displayed as folders in OBS console.

+
+

Restrictions

  • To create a folder, you must be the bucket owner or have the required permission (obs:object:PutObject in IAM or PutObject in a bucket policy).
  • To create a multi-level folder, you only need to create the folder with the last level. For example, if you want to create a folder named src1/src2/src3/, create it directly. You do not need to create folders src1/ and src1/src2/ first.

AccessControlList.REST_CANNED_PRIVATE

+

Private read/write.

+

A bucket or object can only be accessed by its owner.

+

AccessControlList.REST_CANNED_PUBLIC_READ

+

Public read.

+

If this permission is granted on a bucket, anyone can read the object list, multipart uploads, bucket metadata, and object versions in the bucket.

+

If this permission is granted on an object, anyone can read the content and metadata of the object.

+

AccessControlList.REST_CANNED_PUBLIC_READ_WRITE

+

Public read/write.

+

If this permission is granted on a bucket, anyone can read the object list, multipart uploads, and bucket metadata, and can upload or delete objects, initiate multipart uploads, upload parts, assemble parts, copy parts, and abort multipart upload tasks.

+

If this permission is granted on an object, anyone can read the content and metadata of the object.

+

AccessControlList.REST_CANNED_PUBLIC_READ_DELIVERED

+

Public read on a bucket as well as objects in the bucket.

+

If this permission is granted on a bucket, anyone can read the object list, multipart tasks, and bucket metadata, and can also read the content and metadata of the objects in the bucket.

+

This permission cannot be granted on objects.

+

AccessControlList.REST_CANNED_PUBLIC_READ_WRITE_DELIVERED

+

Public read/write on a bucket as well as objects in the bucket.

+

If this permission is granted on a bucket, anyone can read the object list, multipart uploads, and bucket metadata, and can upload or delete objects, initiate multipart upload tasks, upload parts, assemble parts, copy parts, and abort multipart uploads. They can also read the content and metadata of the objects in the bucket.

This permission cannot be granted on objects.

+

AccessControlList.REST_CANNED_BUCKET_OWNER_FULL_CONTROL

+

If this permission is granted on an object, only the bucket and object owners have the full control over the object.

+

By default, if you upload an object to a bucket owned by another user, the bucket owner does not have the permissions on your object. After you grant this permission to the bucket owner, the bucket owner can have full control over your object.

+

For example, if user A uploads object x to user B's bucket, user B does not have the control over object x. If user A sets bucket-owner-full-control for object x, user B then has the control over object x.

Base64-encoded MD5 value of the object data. It is provided for the OBS server to verify data integrity. The OBS server will compare this MD5 value with the MD5 value calculated based on the object data. If the two values are not the same, HTTP status code 400 is returned.

+

Restrictions:

+
  • The MD5 value of the object must be Base64 encoded.
  • If the MD5 value is not specified, the OBS server will not verify the MD5 value of the object.
+

Value range:

+

Base64-encoded 128-bit MD5 value of the request body calculated according to RFC 1864.

+

userMetadata

+

Map<String, Object>

+

No

+

Explanation:

+

User-defined metadata of the object. To define it, you can add a header starting with x-obs-meta- in the request. In Map, the String key indicates the name of the user-defined metadata that starts with x-obs-meta-, and the Object value indicates the value of the user-defined metadata. To obtain the user-defined metadata of an object, use ObsClient.getObjectMetadata. For details, see Obtaining Object Metadata.

Configuring Object Metadata

+

Function

This API configures metadata for an object when uploading it. Object metadata include the object length, MIME type, MD5 value (for verification), storage class, and custom object metadata. You can configure metadata for an object that is being uploaded in streaming, file-based, or multipart mode or when copying an object.

+
+

Restrictions

  • To configure the metadata of an object when uploading it, you must be the bucket owner or have the required permission (obs:object:PutObject in IAM or PutObject in a bucket policy).
  • An object can have multiple pieces of metadata. The metadata size cannot exceed 8 KB in total.
  • Currently, metadata names cannot contain non-ASCII characters. If such characters are contained in a metadata value, the value must be Base64-encoded.

+

AccessControlList.REST_CANNED_PUBLIC_READ_WRITE

+

Public read/write.

+

If this permission is granted on a bucket, anyone can read the object list, multipart uploads, and bucket metadata, and can upload or delete objects, initiate multipart uploads, upload parts, assemble parts, copy parts, and abort multipart upload tasks.

+

If this permission is granted on an object, anyone can read the content and metadata of the object.

+

AccessControlList.REST_CANNED_PUBLIC_READ_DELIVERED

+

Public read on a bucket as well as objects in the bucket.

+

If this permission is granted on a bucket, anyone can read the object list, multipart tasks, and bucket metadata, and can also read the content and metadata of the objects in the bucket.

+

This permission cannot be granted on objects.

+

AccessControlList.REST_CANNED_PUBLIC_READ_WRITE_DELIVERED

+

Public read/write on a bucket as well as objects in the bucket.

+

If this permission is granted on a bucket, anyone can read the object list, multipart uploads, and bucket metadata, and can upload or delete objects, initiate multipart upload tasks, upload parts, assemble parts, copy parts, and abort multipart uploads. They can also read the content and metadata of the objects in the bucket.

Configuring Lifecycle Rules

+

Function

You can configure lifecycle rules to periodically delete objects or transition objects between storage classes. The object expiration time set using this API takes precedence over that set in a bucket lifecycle rule.

+

You can also set the object expiration time when uploading an object or initiating a multipart upload.

+
  • Objects in the Warm storage class have a minimum storage period of 30 days and those in the Cold storage class have a minimum storage period of 90 days. After an object is transitioned to the Cold storage class, if it stays in this storage class for less than 90 days, you still need to pay for a full 90 days.
+
+
+

Restrictions

  • There is no limit on the number of lifecycle rules in a bucket, but the total size of XML descriptions about all lifecycle rules in a bucket cannot exceed 20 KB.
  • A maximum of 20 lifecycle rules can be configured for a parallel file system.
  • To configure a lifecycle rule for a bucket, you must be the bucket owner or have the required permission (obs:bucket:PutLifecycleConfiguration in IAM or PutLifecycleConfiguration in a bucket policy).
  • This API only specifies the time duration in days after which an object will expire. The OBS server automatically clears expired objects.

AccessControlList.REST_CANNED_PRIVATE

+

Private read/write.

+

A bucket or object can only be accessed by its owner.

+

AccessControlList.REST_CANNED_PUBLIC_READ

+

Public read.

+

If this permission is granted on a bucket, anyone can read the object list, multipart uploads, bucket metadata, and object versions in the bucket.

+

If this permission is granted on an object, anyone can read the content and metadata of the object.

+

AccessControlList.REST_CANNED_PUBLIC_READ_WRITE

+

Public read/write.

+

If this permission is granted on a bucket, anyone can read the object list, multipart uploads, and bucket metadata, and can upload or delete objects, initiate multipart uploads, upload parts, assemble parts, copy parts, and abort multipart upload tasks.

+

If this permission is granted on an object, anyone can read the content and metadata of the object.

+

AccessControlList.REST_CANNED_PUBLIC_READ_DELIVERED

+

Public read on a bucket as well as objects in the bucket.

+

If this permission is granted on a bucket, anyone can read the object list, multipart tasks, and bucket metadata, and can also read the content and metadata of the objects in the bucket.

+

This permission cannot be granted on objects.

+

AccessControlList.REST_CANNED_PUBLIC_READ_WRITE_DELIVERED

+

Public read/write on a bucket as well as objects in the bucket.

+

If this permission is granted on a bucket, anyone can read the object list, multipart uploads, and bucket metadata, and can upload or delete objects, initiate multipart upload tasks, upload parts, assemble parts, copy parts, and abort multipart uploads. They can also read the content and metadata of the objects in the bucket.

+

AccessControlList.REST_CANNED_BUCKET_OWNER_FULL_CONTROL

+

If this permission is granted on an object, only the bucket and object owners have the full control over the object.

+

By default, if you upload an object to a bucket owned by another user, the bucket owner does not have the permissions on your object. After you grant this permission to the bucket owner, the bucket owner can have full control over your object.

+

For example, if user A uploads object x to user B's bucket, user B does not have the control over object x. If user A sets bucket-owner-full-control for object x, user B then has the control over object x.

Uploading an Object - Append

+

Function

  1. This API uploads a file or folder to an existing OBS bucket. These files can be texts, images, videos, or any other type of files.
  2. The appendObject operation adds data to the end of an object in a specified bucket. If there is no object with the same names in the bucket, a new object is created. The latest modification time of the object is updated each time an upload is appended.
  3. After an appendable upload is successful, you can call AppendObjectResult.getNextPosition or use the ObsClient.getObjectMetadata API to get the start position for next appending.
+
+

Restrictions

  • To upload an object, you must be the bucket owner or have the required permission (obs:object:PutObject in IAM or PutObject in a bucket policy).
  • The size of each append upload cannot exceed 5 GB.
  • A maximum of 10,000 appendable uploads can be performed on a single object. If you attempt to append more than 10,000 uploads to an object, OBS returns 409 Conflict with an error code ObjectNotAppendable.
  • If the object storage class is COLD (Cold), this API cannot be called.
  • Objects uploaded using ObsClient.putObject, referred to as common objects, can overwrite objects uploaded using ObsClient.appendObject, referred to as appendable objects. Data cannot be appended to an appendable object anymore once the object has been overwritten by a common object.
  • You can append data to an existing object only if it is appendable. Otherwise, an exception will be reported (HTTP status code 409). To check whether an object is appendable, see Obtaining Object Metadata.

Uploading an Object - Resumable

+

Function

The resumable upload is an encapsulated and enhanced version of the multipart upload used for dealing with possible upload failures of large files when the network connection is unstable or a program crashes. This API splits the file into multiple parts and uploads them individually. The upload result of each part is recorded in a checkpoint file in real time. A success message is returned only when all parts are uploaded. If any parts fail, an error message is returned telling you to call the API again to upload the failed parts. Since the checkpoint file contains the progress of each part, it saves you uploading all parts again in the event of an error.

+
+

Restrictions

  • To upload an object, you must be the bucket owner or have the required permission (obs:object:PutObject in IAM or PutObject in a bucket policy).
  • The file uploaded by the resumable upload API must exceed 100 KB.
  • To obtain the progress of the last upload, you must enable resumable upload when you use this API.

Uploading an Object - Browser-Based

+

Function

This API uploads an object up to 5 GB to a specified bucket in HTML form.

+

You can call ObsClient.createPostSignature to generate request parameters for a browser-based upload. The procedure is as follows:

+
  1. Call ObsClient.createPostSignature to generate request parameters for authentication.
  2. Prepare an HTML form.
  3. Enter the request parameters in the page.
  4. Select a local file and upload it in browser-based mode.
+

There are two request parameters generated for authentication:

+
  • Policy, which corresponds to the policy parameter in the form
  • Signature, which corresponds to the signature parameter in the form
+
+
+

Restrictions

  • To upload an object, you must be the bucket owner or have the required permission (obs:object:PutObject in IAM or PutObject in a bucket policy).
+
  • Values of policy and signature in the HTML form are obtained from the returned results of ObsClient.createPostSignature.
  • During the object upload, the value of contentType needs to be manually changed to the corresponding Content-Type value.
+
+

Multipart Upload Overview

+

Function

You can upload large files using multipart upload. Multipart upload is applicable to many scenarios, including:

+
  • Files to be uploaded are larger than 100 MB.
  • The network condition is poor. Connection to the OBS server is constantly down.
  • Sizes of files to be uploaded are uncertain.
+

+

A multipart upload has the following advantages:

+
  • Higher throughput: You can upload parts in parallel to improve throughput.
  • Quick recovery from network failures: Uploading an object in parts helps minimize the impact of upload interruptions caused by network failures.
  • Flexible suspension and resumption of object uploads: You can upload parts at any time. A multipart upload will not expire after being initiated. You must explicitly complete or abort a multipart upload.
  • No need to know the size before uploading an object: You can upload an object while creating it.
+

+

A multipart upload consists of the following steps:

+
  1. Initiate a multipart upload (ObsClient.initiateMultipartUpload).
  2. Upload parts one by one or concurrently (ObsClient.uploadPart).
  3. Assemble parts (ObsClient.completeMultipartUpload) or abort the multipart upload (ObsClient.abortMultipartUpload).

Uploading a Part

+

Function

After a multipart upload is initiated, this API uploads a part to a specified bucket. In the upload request, the multipart upload ID must be included. Except for the part lastly being uploaded whose size ranges from 0 to 5 GB, sizes of the other parts range from 100 KB to 5 GB. Part numbers can be any number from 1 to 10,000.

+

When uploading a part, you must specify its upload ID and part number. A part number uniquely identifies a part and its position in the object you are uploading. If you upload a new part with the same part number as that of a previous part, the previously uploaded part will be overwritten. Whenever you upload a part, OBS returns the ETag header in the response. For each part upload task, you must record the part number and ETag value. These values are required in subsequent requests for you to complete a multipart upload.

+
+

Restrictions

  • To upload a part, you must be the bucket owner or have the required permission (obs:object:PutObject in IAM or PutObject in a bucket policy).
  • After initiating a multipart upload and uploading one or more parts, you must assemble the parts or abort the multipart upload.
  • partNumber in a multipart upload must be unique. When the same partNumber of the same object is concurrently uploaded, last write wins policy is applied. The time of last write is defined as the time when the part metadata is created. To ensure data accuracy, the client must be locked to ensure concurrent uploads of the same part of the same object. Concurrent uploads for different parts of the same object do not need to be locked.

Assembling Parts

+

Function

This API assembles the uploaded parts to complete the multipart upload. Before performing this operation, you cannot download the uploaded data. When assembling parts, you need to copy the additional message header information recorded during the multipart upload initiation to the object metadata. Such information is processed the same way the information in a common object upload is processed. In the case of assembling parts concurrently, last write wins is applied, but the time of last write is defined as the time when a multipart upload was initiated.

+

As long as the multipart upload is not aborted, all uploaded parts occupy the space. However, after you assembled the specified parts, those uploaded but not assembled will be deleted to free up space.

+

When assembling parts, OBS creates an object by putting part numbers in ascending order. If any object metadata is provided in the initiation of the multipart upload, OBS will associate the metadata with the object. After the multipart upload is complete, the parts will no longer exist. A part assembling request must contain the upload ID, part numbers, and a list of corresponding ETag values. In response to the request, the ETag that uniquely identifies the assembled parts is contained. This ETag is not the MD5 hash value of the entire object.

+
+

Restrictions

  • To assemble parts, you must be the bucket owner or have the required permission (obs:object:PutObject in IAM or PutObject in a bucket policy).
  • After a multipart upload is complete, the uploaded parts that are not assembled will be automatically deleted and cannot be recovered. Before assembling parts, use the API for listing uploaded parts to check all parts to ensure that no part is missed.

etag

+

String

+

Explanation:

+

Base64-encoded, 128-bit MD5 value of an object. ETag is the unique identifier of the object content. It can be used to determine whether the object content is changed. For example, if the ETag is A when an object is uploaded and is B when the object is downloaded, the object content is changed. The ETag reflects changes to the contents of the object, not its metadata. An object created by an upload or copy operation has a unique ETag.

+

Restrictions:

The value must contain 32 characters.

+

Default value:

+

None

+

bucketName

+

String

+

Explanation:

+

  • A bucket name:
    • Must be 3 to 63 characters long and start with a digit or letter. Lowercase letters, digits, hyphens (-), and periods (.) are allowed.
    • Cannot be formatted as an IP address.
    • Cannot start or end with a hyphen (-) or period (.).
    • Cannot contain two consecutive periods (..), for example, my..bucket.
    • Cannot contain periods (.) and hyphens (-) adjacent to each other, for example, my-.bucket or my.-bucket.
    +
  • If you repeatedly create buckets of the same name in the same region, no error will be reported and the bucket attributes comply with those set in the first creation request.
+

Default value:

+

None

+

objectKey

+

Code Example of a Multipart Upload

+

Multipart upload is mainly used for large file upload or when the network connection is poor.

+

You can use UploadPartRequest.setOffset and UploadPartRequest.setPartSize to set the start and end positions for uploading a part.

+

This example uploads a large file by concurrently uploading parts.

Aborting a Multipart Upload

+

Function

This API aborts a multipart upload using the multipart upload ID.

+

After a multipart upload is aborted, the upload ID cannot be used to upload any part. The storage occupied by any uploaded parts will be released. If any part uploads are in progress, aborting the multipart upload might or might not make the uploads successful. To release the storage occupied by all uploaded parts, you can only abort the multipart upload after all parts have been uploaded.

+
+

Restrictions

  • To abort a multipart upload, you must be the bucket owner or have the required permission (obs:object:AbortMultipartUpload in IAM or AbortMultipartUpload in a bucket policy).
+
+

Method

Listing Multipart Uploads

+

Function

This API lists ongoing multipart uploads.

+

Ongoing multipart uploads are the multipart uploads that have been initiated but have not been completed or aborted. A maximum of 1,000 multipart uploads can be returned in a response. If there are over 1,000 ongoing tasks satisfying the list criteria, you need to send more requests to query additional multipart uploads.

+
+

Restrictions

  • To list multipart uploads, you must be the bucket owner or have the required permission (obs:bucket:ListBucketMultipartUploads in IAM or ListBucketMultipartUploads in a bucket policy).
  • By default, only the bucket owner and multipart upload initiator have this permission. The bucket owner can grant others the ListBucketMultipartUploads permission.
+
+

Method

obsClient.listMultipartUploads(ListMultipartUploadsRequest request)

Downloading an Object - Streaming

+

Function

When you call ObsClient.getObject, an instance of ObsObject will be returned. This instance contains the contents of the object such as its name, attributes, input stream, and which bucket it is stored in. You can perform operations on the object input stream to read the contents to a local file or memory.

+
+

Restrictions

  • To download an object, you must be the bucket owner or have the required permission (obs:object:GetObject in IAM or GetObject in a bucket policy).
  • Objects in the Cold storage class can be downloaded only when they are restored.
  • Object input streams obtained by ObsObject.getObjectContent must be closed explicitly. Otherwise, resource leakage occurs.
+
+

Method

obsClient.getObject(GetObjectRequest request)

+
+

Downloading an Object - Range-Based

+

Function

This API downloads partial data of an object by specifying a range. If the specified range is from 0 to 1,000, data from byte 0 to byte 1,000, 1,001 bytes in total, are returned. If the specified range is invalid, the whole object is returned.

+
+

Restrictions

  • To download an object, you must be the bucket owner or have the required permission (obs:object:GetObject in IAM or GetObject in a bucket policy).
  • Objects in the Cold storage class can be downloaded only when they are restored.
  • If the specified range is invalid (for example, the start or end position is set to a negative integer, or the start position is greater than the end position), the API throws an exception. If the specified range is valid and the end position is greater than the object size, the entire object is returned.

Downloading an Object - Resumable

+

Function

  1. Downloading large files often fails due to an unstable network or program breakdown. It is a waste of resources to download files again. Moreover, the restarted download may still fail due to an unstable network. To resolve such issues, the resumable download API splits the file to be downloaded into multiple parts and downloads them separately. The download result of each part is recorded in a checkpoint file in real time. Only when all parts are downloaded is a message indicating the download is successful returned. If any parts fail to be downloaded, a message is returned telling you to call the API again to download the failed parts. Since the checkpoint file contains the progress of all parts, it helps you avoid downloading all parts in re-downloads, so that you can enjoy a cost-effective, efficient download.
  2. The resumable download API is an encapsulated and enhanced version of the API for partial download. For details about the partial download, see Downloading an Object - Range-Based.
  3. This API saves resources and improves efficiency upon the re-download, and speeds up the download process by concurrently downloading parts. You do not need to worry about internal service details, such as the creation and deletion of checkpoint files, division of objects, or concurrent downloads of parts.
+
+

Restrictions

  • To download an object, you must be the bucket owner or have the required permission (obs:object:GetObject in IAM or GetObject in a bucket policy).

Obtaining Object Metadata

+

Function

Object metadata is a set of name-value pairs that describe the object and is used for object management.

+

Users with the READ permission on objects can send HEAD requests to retrieve metadata from objects. The metadata of the objects is included in the response.

+

This operation supports server-side encryption.

+
+

Restrictions

  • To obtain object metadata, you must be the bucket owner or have the required permission (obs:object:GetObject in IAM or GetObject in a bucket policy).
  • You can also call metadata.getOriginalHeaders to obtain information about all original response headers.
+
+

Method

obsClient.getObjectMetadata(GetObjectMetadataRequest request)

Configuring an Object ACL

+

Function

Access control lists (ACLs) allow resource owners to grant other accounts the permissions to access resources. By default, only the resource owner has full control over resources when a bucket or object is created. That is, the bucket creator has full control over the bucket, and the object uploader has full control over the object. Other accounts do not have the permissions to access resources. If resource owners want to grant other accounts the read and write permissions on resources, they can use ACLs. ACLs grant permissions to accounts. After an account is granted permissions, both the account and its IAM users can access the resources. If an object is encrypted with SSE-KMS, the ACL configured for it is not in effect in the cross-tenant case.

+

+
+

An object ACL can be configured in any of the following ways:

+
  1. Code Example: Setting a Pre-defined ACL When Uploading the Object
  2. Code Example: Setting a Pre-defined ACL for the Object
  3. Code Example: Setting an ACL for the Object Directly
+

Restrictions

  • To configure an object ACL, you must be the bucket owner or have the required permission (obs:object:PutObjectAcl in IAM or PutObjectAcl in a bucket policy).
  • An object can have a maximum of 100 rules in its ACL.

+

This permission cannot be granted on objects.

+

AccessControlList.REST_CANNED_PUBLIC_READ_WRITE_DELIVERED

+

Public read/write on a bucket as well as objects in the bucket.

+

If this permission is granted on a bucket, anyone can read the object list, multipart uploads, and bucket metadata, and can upload or delete objects, initiate multipart upload tasks, upload parts, assemble parts, copy parts, and abort multipart uploads. They can also read the content and metadata of the objects in the bucket.

+

This permission cannot be granted on objects.

+

AccessControlList.REST_CANNED_BUCKET_OWNER_FULL_CONTROL

+

If this permission is granted on an object, only the bucket and object owners have the full control over the object.

+

By default, if you upload an object to a bucket owned by another user, the bucket owner does not have the permissions on your object. After you grant this permission to the bucket owner, the bucket owner can have full control over your object.

+

For example, if user A uploads object x to user B's bucket, user B does not have the control over object x. If user A sets bucket-owner-full-control for object x, user B then has the control over object x.

Listing Objects

+

Function

This API lists some or all of the objects in a bucket. You can use parameters such as the prefix, number of returned objects, and start position to list objects that meet specified criteria. Returned objects are listed in alphabetical order by object name.

+
+

Restrictions

  • To list objects in a bucket, you must be the bucket owner or have the required permission (obs:bucket:ListBucket in IAM or ListBucket in a bucket policy).
  • A maximum of 1,000 object versions can be returned in a single request. If a bucket contains more than 1,000 object versions, you can use pagination to list all versions. If ListVersionsResult.isTruncated is true, only part of object versions are returned. In this case, you can use ListVersionsResult.getNextKeyMarker and ListVersionsResult.getNextVersionIdMarker to obtain the start position for the next listing.
+
+

Explanation:

+

Object names are grouped by this parameter, which is often used with Prefix. If a prefix is specified, objects with the same string from the prefix to the first delimiter are grouped into one CommonPrefixes. If no prefix is specified, objects with the same string from the first character to the first delimiter are grouped into one CommonPrefixes.

+

Assume that a bucket has objects abcd, abcde, and bbcde in it. If delimiter is set to d and prefix is set to a, files abcd and abcde are grouped into a CommonPrefixes with abcd as the prefix. If only delimiter is set to d, files abcd and abcde are grouped into a CommonPrefixes with abcd as the prefix, and bbcde is grouped separately into another CommonPrefixes with bbcd as the prefix.

+

For a PFS, if this parameter is not specified, all the contents in the current directory are recursively listed by default, and subdirectories are also listed. In big data scenarios, PFSs usually have multiple directory levels and each directory level has a large number of files. In such case, you are advised to configure [delimiter=/] to list the contents in the current directory but exclude the contents in subdirectories, thereby accelerating the listing.

+

Value range:

+

The value must contain 1 to 1,024 characters.

+

Default value:

+

None

Code Example: Listing Objects in a Folder

There is no concept of folders in OBS. All elements stored in OBS buckets are objects. Folders are actually objects whose sizes are 0 and whose names end with a slash (/). You can set a folder name as a prefix to list objects in this folder. This example lists objects in a folder.

  • The sample code does not apply to scenarios where the number of objects in a folder exceeds 1,000.
  • Since all folder names end with a slash (/) and the objects and sub-folders to list are under the folder, delimiter is always a slash (/).
  • In the returned result of each recursion, ObjectListing.getObjects includes the objects under the folder, and ObjectListing.getCommonPrefixes includes the sub-folders under the folder.

Copying an Object

+

Function

This API copies an object stored in OBS to another path, with a copy created during the process. You can create a copy of an object up to 5 GB in a single operation.

+
+

Restrictions

  • To copy an object, you must be the bucket owner or have the required permission (obs:object:PutObject in IAM or PutObject in a bucket policy).
  • You must have the read permission on the source object.
  • The object copy request carries the information about the source bucket and object to be copied in the header field. The message body cannot be carried.
  • Cross-bucket replication in the same region is supported, but cross-region replication is not supported.
  • An object copy can be up to 5 GB in size. If the source object exceeds 5 GB, you can only perform a multipart copy.
  • If the source object is in the Cold storage class, you must restore it first.

+

Public read.

+

If this permission is granted on a bucket, anyone can read the object list, multipart uploads, bucket metadata, and object versions in the bucket.

+

If this permission is granted on an object, anyone can read the content and metadata of the object.

+

AccessControlList.REST_CANNED_PUBLIC_READ_WRITE

+

Public read/write.

+

If this permission is granted on a bucket, anyone can read the object list, multipart uploads, and bucket metadata, and can upload or delete objects, initiate multipart uploads, upload parts, assemble parts, copy parts, and abort multipart upload tasks.

+

If this permission is granted on an object, anyone can read the content and metadata of the object.

+

AccessControlList.REST_CANNED_PUBLIC_READ_DELIVERED

+

Public read on a bucket as well as objects in the bucket.

+

If this permission is granted on a bucket, anyone can read the object list, multipart tasks, and bucket metadata, and can also read the content and metadata of the objects in the bucket.

+

This permission cannot be granted on objects.

+

AccessControlList.REST_CANNED_PUBLIC_READ_WRITE_DELIVERED

+

Public read/write on a bucket as well as objects in the bucket.

String

+

Explanation:

+

ETag of the target object. Base64-encoded, 128-bit MD5 value of an object. ETag is the unique identifier of the object contents and is used to determine whether the contents of an object are changed. For example, if the ETag value is A when an object is uploaded and is B when the object is downloaded, this indicates the contents of the object are changed. The ETag reflects changes only to the contents of an object, not its metadata. Objects created by the upload and copy operations have unique ETags after being encrypted using MD5.

Configuring Object Metadata

+

Function

Object metadata is a set of name-value pairs that describe the object and is used for object management.

+

Currently, only the system-defined metadata is supported.

+

There are two kinds of metadata: system-controlled metadata and user-controlled metadata. The kind of metadata like Last-Modified is controlled by the system and cannot be modified. However, the kind of metadata configured for objects such as ContentLanguage can be modified by calling APIs.

+

This API sends a HEAD request to configure the metadata of an object in a specified bucket.

+
+

Restrictions

  • To configure object metadata, you must be the bucket owner or have the required permission (obs:object:ModifyObjectMetaData in IAM or ModifyObjectMetaData in a bucket policy).
  • An object can have multiple pieces of metadata. The size of the metadata cannot exceed 8 KB in total.
  • Currently, metadata names only support ASCII characters. Non-ASCII characters must be Base64-encoded.
  • If versioning is enabled for a bucket, you can set metadata for objects of the latest version, but cannot set metadata for noncurrent objects.
  • You cannot set metadata for Cold objects.
  • If a folder or directory is an actual object in an object bucket, their metadata can be modified. If a directory is a simulated directory, for example, test/ in the test/test1.txt object, the metadata of this simulated directory cannot be modified.
+
+

Method

obsClient.setObjectMetadata(SetObjectMetadataRequest request)

Table 2 SetObjectMetadataRequest

Parameter

+

Type

+

Mandatory (Yes/No)

+

Description

+

bucketName

+

String

+

Yes

+

Explanation:

+

Bucket name.

+

Restrictions:

+
  • A bucket name must be unique across all accounts and regions.
  • A bucket name:
    • Must be 3 to 63 characters long and start with a digit or letter. Lowercase letters, digits, hyphens (-), and periods (.) are allowed.
    • Cannot be formatted as an IP address.
    • Cannot start or end with a hyphen (-) or period (.).
    • Cannot contain two consecutive periods (..), for example, my..bucket.
    • Cannot contain periods (.) and hyphens (-) adjacent to each other, for example, my-.bucket or my.-bucket.
    +
  • If you repeatedly create buckets of the same name in the same region, no error will be reported and the bucket attributes comply with those set in the first creation request.
+

Default value:

+

None

+

objectKey

+

String

+

Yes

+

Explanation:

+

Object name. An object is uniquely identified by an object name in a bucket. An object name is a complete path that does not contain the bucket name.

+

Value range:

+

The value must contain 1 to 1,024 characters.

+

Default value:

+

None

+

versionId

+

String

+

No

+

Explanation:

+

Object version ID.

+

Value range:

+

The value must contain 32 characters.

+

Default value:

+

None

+

storageClass

+

StorageClassEnum

+

No

+

Explanation:

+

Storage class of the object.

+

Value range:

+

See Table 3.

+

Default value:

+

None

+

removeUnset

+

boolean

+

No

+

Explanation:

+

Whether to delete the previously configured metadata if the request is successful.

+

Value range:

+

true: If the API is successfully invoked, the previous metadata will be deleted. Standard metadata is not affected. For user-defined metadata, only the new metadata is retained.

+

false: The previous metadata will not be deleted even if the API is successfully invoked. Standard metadata is not affected. For user-defined metadata, only the new metadata is retained.

+

Default value:

+

false

+

userMetadata

+

Map<String, String>

+

No

+

Explanation:

+

User-defined metadata of the object. To define it, you can add a header starting with x-obs-meta- in the request. In Map, the String key and value indicate the name and value of the user-defined metadata respectively. After the metadata is defined, when you later download the object or query its metadata, the user-defined metadata is returned in the response.

+

Restrictions:

+
  • The user-defined metadata cannot exceed 8 KB in total. To measure the size, calculate the sum of bytes of all UTF-8 encoded keys and values.
  • The user-defined metadata keys are case insensitive, because OBS converts the uppercase keys to lowercase for storage. However, the metadata values are case sensitive.
  • Both user-defined metadata keys and their values must conform to US-ASCII standards. If non-ASCII or unrecognizable characters are necessary, they must be encoded and decoded in URL or Base64 on the client, because the server side does not perform any decoding.
+

Default value:

+

None

+

userHeaders

+

HashMap<String, String>

+

No

+

Explanation:

+

User header list. In HashMap, the String key and value indicate the name and value of the user header field respectively. The SDK does not process the userHeaders and instead transparently transmits it to the server for later use.

+

Default value:

+

None

+

encodeHeaders

+

boolean

+

No

+

Explanation:

+

Whether to enable OBS to automatically encode request headers.

+

Value range:

+

true: Encoding with SDK is enabled.

+

false: Encoding with SDK is disabled.

+

Default value:

+

true

+

replaceMetadata

+

ObjectRepleaceMetadata

+

No

+

Explanation:

+

It specifies the metadata returned when the object is downloaded. For details, see Table 4.

+

webSiteRedirectLocation

+

String

+

No

+

Explanation:

+

If the bucket is configured with website hosting, the request for obtaining the object can be redirected to another object in the bucket or an external URL.

+

The request is redirected to an object anotherPage.html in the same bucket:

+

WebsiteRedirectLocation:/anotherPage.html

+

The request is redirected to an external URL http://www.example.com/:

+

WebsiteRedirectLocation:http://www.example.com/

+

OBS obtains the specified value from the header and stores it in the object metadata WebsiteRedirectLocation.

+

Restrictions:

+
  • The value must start with a slash (/), http://, or https:// and cannot exceed 2 KB.
  • OBS only supports redirection for objects in the root directory of a bucket.
+

Default value:

+

None

+
+

After you run the sample code above and configure the user-defined metadata property1 and user headers property2 and x-obs-meta-property3, the HTTP header in the packet capture is as follows:

+

+
+

Code Example: Deleting Metadata for the Object

If you want to delete some metadata by calling the API for setting object metadata, configure the metadata to be retained and set SetObjectMetadataRequest.setRemoveUnset to true. Then, once the API is called, the data whose metadata is not configured will be deleted. Therefore, exercise caution when using SetObjectMetadataRequest.setRemoveUnset(true).

+

This example deletes the user-defined metadata of object objectname in bucket examplebucket.

Obtaining an Object ACL

+

Function

Access control lists (ACLs) allow resource owners to grant other accounts the permissions to access resources. By default, only the resource owner has full control over resources when a bucket or object is created. That is, the bucket creator has full control over the bucket, and the object uploader has full control over the object. Other accounts do not have the permissions to access resources. If resource owners want to grant other accounts the read and write permissions on resources, they can use ACLs. ACLs grant permissions to accounts. After an account is granted permissions, both the account and its IAM users can access the resources. If an object is encrypted with SSE-KMS, the ACL configured for it is not in effect in the cross-tenant case.

+

+

This API obtains the ACL of an object in a specified bucket.

+
+

Restrictions

  • To obtain an object ACL, you must be the bucket owner or have the required permission (obs:object:GetObjectAcl in IAM or GetObjectAcl in a bucket policy).

Batch Deleting Objects

+

Function

This API deletes objects in batches from a specific bucket. Deleted objects cannot be recovered.

+

In a batch delete operation, OBS concurrently deletes the specified objects and returns the deletion result of each object.

+
+

Restrictions

  • To delete objects in a batch, you must be the bucket owner or have the required permission (obs:object:DeleteObject in IAM or DeleteObject in a bucket policy).
  • If versioning is not enabled for a bucket, deleted objects cannot be recovered.
  • A maximum of 1,000 objects can be deleted at a time. If you send a request for deleting more than 1,000 objects, OBS returns an error message.
  • After concurrent tasks are assigned, if an internal error occurs during cyclic deletion of multiple objects, an object may be deleted in the index data but still exist in the metadata.
+
+

Copying an Object - Multipart

+

Function

This API allows you to upload a part by copying an object or part of this object.

+

You can call ObsClient.copyPart to copy parts.

+
+

Restrictions

  • To copy an object, you must be the bucket owner or have the required permission (obs:object:PutObject in IAM or PutObject in a bucket policy).
  • You must have the read permission on the source object.
  • The object copy request carries the information about the source bucket and object to be copied in the header field. The message body cannot be carried.
  • Cross-bucket replication in the same region is supported, but cross-region replication is not supported.
  • If the source object is in the Cold storage class, you must restore it first.
+
+

ETag of an object, which is a Base64-encoded 128-bit MD5 digest. ETag is the unique identifier of the object content. It can be used to determine whether the object content is changed. For example, if the ETag is A when an object is uploaded and is B when the object is downloaded, the object content is changed. The ETag reflects changes only to the contents of the object, not its metadata. An object created by an upload or copy operation has a unique ETag.

+

Restrictions:

+

If an object is encrypted using server-side encryption, the ETag is not the MD5 value of the object.

+

Value range:

+

The value must contain 32 characters.

+

Default value:

+

None

+

Accessing OBS Using a Signed URL

+

Function

ObsClient allows you to create a URL with Query parameters that carry authentication information by specifying the AK and SK, HTTP method, and request parameters. You can provide this URL to other users for them to make a temporary access. When generating a URL, you need to specify the validity period of the URL to restrict the access duration of visitors.

+

If you want to grant other users the permission to perform operations on buckets or objects (for example, upload or download objects), you need to generate a URL for the corresponding request (for example, a URL with the PUT request for uploading an object) and provide the URL to other users.

+
If a CORS or signature mismatch error occurs, refer to the following steps to troubleshoot the issue:
  1. If CORS is not configured, you need to configure CORS rules on OBS Console.
  2. If the signatures do not match, check whether signature parameters are correct. For example, during an object upload, the backend uses Content-Type to calculate the signature and generate an authorized URL, but if Content-Type is not set or is set to an incorrect value when the frontend uses the authorized URL, a CORS error occurs. To avoid this issue, ensure that Content-Type fields are the same at the frontend and backend.
  3. A CDN acceleration domain name cannot be used to create a signed URL.

To access OBS using a signed URL generated by the OBS SDK for Java, perform the following steps:

+
  1. Use ObsClient.createTemporarySignature to create a signed URL. Note that the ObsClient.createTemporarySignature function has encoded the generated URL. The browser will automatically decode the URL. You do not need to encode it again.
  2. Use an HTTP library to make an HTTP/HTTPS request to OBS.
+

Overview

+

You can use versioning to store multiple versions of an object in a bucket.

+

When versioning is enabled for a bucket, OBS keeps multiple versions of an object in the bucket, allowing you to easily retrieve and restore historical versions or recover data in the event of accidental changes or application failures.

+

By default, versioning is disabled for new OBS buckets. In this case, if a newly uploaded object is using the name of the previously uploaded one, the new object will overwrite the previous one.

+

For details about different versioning operations, see:

Configuring Versioning for a Bucket

+

Function

You can enable versioning to automatically maintain previous versions of an object. When versioning is enabled, you can access earlier versions of an object to recover your data in the event of accidental actions or application failures.

+

This API configures the versioning status for a bucket.

+
+

Restrictions

  • To configure versioning for a bucket, you must be the bucket owner or have the required permission (obs:bucket:PutBucketVersioning in IAM or PutBucketVersioning in a bucket policy).
+
+

Method

obsClient.setBucketVersioning(final SetBucketVersioningRequest request)

Copying an Object Version

+

Function

This API copies an object version in a specified bucket.

+

You can call ObsClient.copyObject to copy an object version by specifying the version ID (versionId).

+
+

Restrictions

  • To copy an object, you must be the bucket owner or have the required permission (obs:object:PutObject in IAM or PutObject in a bucket policy).
  • You must have the read permission on the source object.
  • The object copy request carries the information about the source bucket and object to be copied in the header field. The message body cannot be carried.
  • Cross-bucket replication in the same region is supported, but cross-region replication is not supported.
  • An object copy can be up to 5 GB in size. If the source object exceeds 5 GB, you can only perform a multipart copy.
  • If the source object is in the Cold storage class, you must restore it first.

See Table 16.

+

Default value:

+

None

+

webSiteRedirectLocation

+

String

+

No

+

Explanation:

+

If the bucket is configured with website hosting, the request for obtaining the object can be redirected to another object in the bucket or an external URL. This parameter specifies the address the request for the object is redirected to.

+

The request is redirected to an object anotherPage.html in the same bucket:

+

WebsiteRedirectLocation:/anotherPage.html

+

The request is redirected to an external URL http://www.example.com/:

+

WebsiteRedirectLocation:http://www.example.com/

+

+

etag

+

String

+

Explanation:

+

ETag of the target object. Base64-encoded, 128-bit MD5 value of an object. ETag is the unique identifier of the object contents and is used to determine whether the contents of an object are changed. For example, if the ETag value is A when an object is uploaded and is B when the object is downloaded, this indicates the contents of the object are changed. The ETag reflects changes only to the contents of an object, not its metadata. Objects created by the upload and copy operations have unique ETags after being encrypted using MD5.

Listing Object Versions

+

Function

This API lists some or all of the object versions in a bucket. When listing the object versions, you can specify the criteria such as the prefix, number, and start position. Returned object versions are listed in alphabetical order by object name.

+

The returned results of ObsClient.listVersions include the object versions and delete markers.

+
+

Restrictions

  • To list object versions in a bucket, you must be the bucket owner or have the required permission (obs:bucket:ListBucketVersions in IAM or ListBucketVersions in a bucket policy).
  • A maximum of 1,000 object versions can be returned in a single request. If a bucket contains more than 1,000 object versions, you can use pagination to list all versions. If ListVersionsResult.isTruncated is true, only part of object versions are returned. In this case, you can use ListVersionsResult.getNextKeyMarker and ListVersionsResult.getNextVersionIdMarker to obtain the start position for the next listing.

Table 2 ListVersionsRequest parameters

Parameter

+

Type

+

Mandatory (Yes/No)

+

Description

+

bucketName

+

String

+

Yes

+

Explanation:

+

Bucket name.

+

Restrictions:

+
  • A bucket name must be unique across all accounts and regions.
  • A bucket name:
    • Must be 3 to 63 characters long and start with a digit or letter. Lowercase letters, digits, hyphens (-), and periods (.) are allowed.
    • Cannot be formatted as an IP address.
    • Cannot start or end with a hyphen (-) or period (.).
    • Cannot contain two consecutive periods (..), for example, my..bucket.
    • Cannot contain periods (.) and hyphens (-) adjacent to each other, for example, my-.bucket or my.-bucket.
    +
  • If you repeatedly create buckets of the same name in the same region, no error will be reported and the bucket attributes comply with those set in the first creation request.
+

Default value:

+

None

+

prefix

+

String

+

No

+

Explanation:

+

Prefix that the names of objects to list must contain.

+

Value range:

+

The value must contain 1 to 1,024 characters.

+

Default value:

+

None

+

keyMarker

+

String

+

No

+

Explanation:

+

Object name to start with when listing object versions in a bucket. All object versions following this parameter are listed in alphabetical order.

+

Restrictions:

+

This parameter is only available for listing objects with multiple versions.

+

Value range:

+

The value of nextKeyMarker in the response body of the last request.

+

Default value:

+

None

+

maxKeys

+

int

+

No

+

Explanation:

+

The maximum number of object versions returned in the response in alphabetical order.

+

Value range:

+

The value ranges from 1 to 1000. If the specified value is beyond this range, only 1,000 objects are returned.

+

Default value:

+

1000

+

delimiter

+

String

+

No

+

Explanation:

+

This parameter is used to group object names. If a prefix is specified, objects with the same string from the prefix to the first delimiter are grouped into one CommonPrefixes. If no prefix is specified, objects with the same string from the first character to the first delimiter are grouped into one CommonPrefixes.

+

Assume that a bucket has objects abcd, abcde, and bbcde in it. If delimiter is set to d and prefix is set to a, objects abcd and abcde are grouped into a commonPrefix with abcd as the prefix. If only delimiter is set to d, objects abcd and abcde are grouped into a commonPrefix with abcd as the prefix, and bbcde is grouped separately into another commonPrefix with bbcd as the prefix.

+

For a PFS, if this parameter is not specified, all the contents in the current directory are recursively listed by default, and subdirectories are also listed. In big data scenarios, PFSs usually have multiple directory levels and each directory level has a large number of files. In such case, you are advised to configure [delimiter=/] to list the contents in the current directory but exclude the contents in subdirectories, thereby accelerating the listing.

+

Value range:

+

The value must contain 1 to 1,024 characters.

+

Default value:

+

None

+

versionIdMarker

+

String

+

No

+

Explanation:

+

Version ID you want to start listing from. All object versions following the value specified by this parameter are listed in alphabetical order by object name and version ID. This parameter must be used together with keyMarker. keyMarker specifies the object name, and versionIdMarker specifies the version of the specified object.

+

Restrictions:

+
  • This parameter is only available for listing objects with multiple versions.
  • If the object version specified by versionIdMarker and the object name specified by keyMarker do not match, versionIdMarker is invalid.
+

Value range:

+

Object version ID, that is, the value of nextVersionIdMarker in the response body of the last request.

+

Default value:

+

None

+

Default value:

+

1000

+

delimiter

+

String

+

Explanation:

+

Object names are grouped by this parameter, which is often used with Prefix. If a prefix is specified, objects with the same string from the prefix to the first delimiter are grouped into one CommonPrefixes. If no prefix is specified, objects with the same string from the first character to the first delimiter are grouped into one CommonPrefixes.

+

Assume that a bucket has objects abcd, abcde, and bbcde in it. If delimiter is set to d and prefix is set to a, files abcd and abcde are grouped into a CommonPrefixes with abcd as the prefix. If only delimiter is set to d, files abcd and abcde are grouped into a CommonPrefixes with abcd as the prefix, and bbcde is grouped separately into another CommonPrefixes with bbcd as the prefix.

+

For a PFS, if this parameter is not specified, all the contents in the current directory are recursively listed by default, and subdirectories are also listed. In big data scenarios, PFSs usually have multiple directory levels and each directory level has a large number of files. In such case, you are advised to configure [delimiter=/] to list the contents in the current directory but exclude the contents in subdirectories, thereby accelerating the listing.

Code Example: Listing All Object Versions in a Folder

There is no concept of folders in OBS. All elements stored in OBS buckets are objects. Folders are actually objects whose sizes are 0 and whose names end with a slash (/). You can set a folder name as a prefix to list objects in this folder. This example lists all object versions in a folder.

  • The code examples above do not involve scenarios where there are more than 1,000 object versions in a folder.
  • Since all folder names end with a slash (/) and the objects and sub-folders to list are under the folder, delimiter is always a slash (/).
  • In the returned result of each recursion, ListVersionsResult.getVersions includes the object versions under the folder, and ListVersionsResult.getCommonPrefixes includes the sub-folders under the folder.

Setting an ACL for an Object Version

+

Function

OBS allows the control of access permissions for objects. By default, only object creators have the read and write permissions on the object. You can set access control policies for objects. For example, if an object is configured with the public access policy, all users are allowed to read the object. If an object is encrypted with SSE-KMS, the ACL configured for it is not in effect in the cross-tenant case.

+

You can set an ACL when uploading an object or call an ACL API to modify or obtain the ACL of an existing object.

+
+

Restrictions

  • To set an object ACL, you must be the bucket owner or have the required permission (obs:object:PutObjectAcl in IAM or PutObjectAcl in a bucket policy).
+
  • An object ACL supports a maximum of 100 grants.
+
+

Obtaining the ACL of an Object Version

+

Function

OBS allows the control of access permissions for objects. By default, only object creators have the read and write permissions on the object. You can call an ACL API to modify or obtain the ACL of an existing object.

+

This API returns the ACL for a specific object version in a bucket.

+
+

Restrictions

  • To obtain an object ACL, you must be the bucket owner or have the required permission (obs:object:GetObjectAcl in IAM or GetObjectAcl in a bucket policy).
+
  • To call this API, you must have the read permission on the ACL of the object.
+
+

Method

obsClient.getObjectAcl(GetObjectAclRequest request)

Batch Deleting Object Versions

+

Function

This API deletes objects in batches from a specific bucket. Deleted objects cannot be recovered.

+

In a batch delete operation, OBS concurrently deletes the specified objects and returns the deletion result of each object.

+

You can call ObsClient.deleteObjects to pass version IDs (versionId) to delete object versions.

+
+

Restrictions

  • To delete objects in a batch, you must be the bucket owner or have the required permission (obs:object:DeleteObject in IAM or DeleteObject in a bucket policy).
  • If versioning is not enabled for a bucket, deleted objects cannot be recovered.
  • A maximum of 1,000 objects can be deleted at a time. If you send a request for deleting more than 1,000 objects, OBS returns an error message.
  • After concurrent tasks are assigned, if an internal error occurs during cyclic deletion of multiple objects, an object may be deleted in the index data but still exist in the metadata.

Overview

+

OBS allows you to set lifecycle rules for buckets to automatically transition the storage class of an object or delete expired objects, to effectively use storage features and optimize the storage space. You can set multiple lifecycle rules based on the prefix. A lifecycle rule must contain:

+
  • Rule ID, which uniquely identifies the rule
  • Prefix of objects that are under the control of this rule
  • Transition policy of an object of the latest version, which can be specified in either mode:
    1. How many days after the object is created
    2. Transition date
    +
  • Expiration time of an object of the latest version, which can be specified in either mode:
    1. How many days after the object is created
    2. Expiration date
    +
  • Transition policy of a noncurrent object version, which can be specified in the following mode:
    • How many days after an object version becomes a noncurrent one
    +
  • Expiration time of a noncurrent object version, which can be specified in the following mode:
    • How many days after the object becomes a noncurrent object version
    +
  • Identifier specifying whether the setting is effective

Setting Lifecycle Rules

+

Function

This API configures lifecycle rules for a bucket to periodically delete objects in the bucket or transition objects between storage classes.

+
  1. An object will be automatically deleted by the OBS server once it expires.
  2. The time set in the transition policy of an object must be earlier than its expiration time, and the time set in the transition policy of a noncurrent object version must be earlier than its expiration time.
  3. The configured expiration time and transition policy for a noncurrent object version can only take effect when versioning is enabled or suspended for the bucket where that object version is stored.
+
  • Objects in the Warm storage class have a minimum storage period of 30 days and those in the Cold storage class have a minimum storage period of 90 days. After an object is transitioned to the Cold storage class, if it stays in this storage class for less than 90 days, you still need to pay for a full 90 days.
+
+
+

Restrictions

  • There is no limit on the number of lifecycle rules in a bucket, but the total size of XML descriptions about all lifecycle rules in a bucket cannot exceed 20 KB.
  • A maximum of 20 lifecycle rules can be configured for a parallel file system.
  • To configure a lifecycle rule for a bucket, you must be the bucket owner or have the required permission (obs:bucket:PutLifecycleConfiguration in IAM or PutLifecycleConfiguration in a bucket policy).
  • Expired objects will be permanently deleted and cannot be recovered.
  • Multi-AZ redundancy is not available for Cold storage. For this reason, buckets or objects with multi-AZ redundancy cannot be transitioned to the Cold storage class based on a lifecycle rule.
+

Overview

+

Cross-origin access refers to access between different domains. Restricting cross-origin access is a browser policy for security purposes, that is, the same-origin policy.

+

Due to this same-origin policy, JavaScript in origin A cannot operate objects in origin B or C.

+

The same-origin policy requires the protocols, domain names (or IP addresses), and ports are all the same. If the protocols, domain names, and ports (if specified) of the two web pages are the same, the two web pages are in the same origin.

+

Cross-origin resource sharing (CORS) allows web application programs in one origin to access resources in another.

+

OBS supports CORS rules that allow the resources in OBS to be requested by other domains.

+

+

For more information about the application scenarios of CORS, see:

Configuring a CORS Rule

+

Function

Cross-origin resource sharing (CORS) is a mechanism defined by the World Wide Web Consortium (W3C) that allows a web application program in one domain to access resources located in another one. For general web page requests, website scripts and contents in one domain cannot interact with those in another because of Same Origin Policies (SOPs). OBS supports CORS rules that allow the resources in OBS to be requested by other domains.

+

You can call ObsClient.setBucketCors to set CORS rules for a bucket. The configured CORS rules follow the principle of new ones overwriting old ones.

+
+

Restrictions

  • To configure CORS for a bucket, you must be the bucket owner or have the required permission (obs:bucket:PutBucketCORS in IAM or PutBucketCORS in a bucket policy).
+
+

Method

obsclient.setBucketCors(final SetBucketCorsRequest request)

+

Deleting a CORS Rule

+

Function

CORS is a browser-standard mechanism defined by the W3C. It allows a web client in one origin to interact with resources in another. For general web page requests, website scripts and contents in one origin cannot interact with those in another due to SOPs. OBS supports CORS, allowing the resources in OBS to be requested across origins.

+

This API deletes the CORS rules of a bucket.

+
+

Restrictions

  • To delete the CORS configuration of a bucket, you must be the bucket owner or have the required permission (obs:bucket:PutBucketCORS in IAM or PutBucketCORS in a bucket policy).
+
+

Method

Overview

+

OBS allows you to configure access logging for buckets. After the configuration, access to buckets will be recorded in logs. These logs will be saved in specific buckets in OBS.

+

You can enable OBS logging for bucket analysis or audit purposes. With access logs, a bucket owner can analyze the characteristics, types, or trends of requests sent to the bucket.

+

With logging enabled, OBS automatically logs access requests for the bucket and writes the generated log files into a specified bucket.

+

You need to specify a bucket for storing log files when enabling logging for a bucket. Log files can be stored in any bucket you own in the region where the logged bucket is, including the logged bucket itself.

Configuring Logging for a Bucket

+

Function

This API enables logging for a bucket (source) and configures another bucket (target) to store the log files. When a bucket is created, logging is not enabled by default. You can call this API to enable logging for the bucket. With logging enabled, a log message is generated for each operation on the bucket. Multiple log messages are packed into a file. The target bucket for storing log files must be specified when logging is enabled. It can be the bucket logging is enabled for, or any other bucket you have access to. If you specify another bucket for storing logs, the bucket must be in the same region as the logged bucket. You can also specify access permissions and name prefixes for log files.

+
+

Restrictions

  • The source and target buckets must be in the same region.
  • A bucket in the Warm or Cold storage class cannot be used as a target bucket.
  • OBS creates log files and uploads them to the bucket. Before enabling logging for a bucket, you need to create an IAM agency to delegate OBS to upload log files to the specified bucket.
  • To configure logging for a bucket, you must be the bucket owner or have the required permission (obs:bucket:PutBucketLogging in IAM or PutBucketLogging in a bucket policy).

Overview

+

To host your static website on OBS, you can upload static website files to your bucket as objects, configure the public read permission for the objects, and then configure static website hosting for your bucket.

+

After this, when third-party users access your websites, they actually access the objects in your bucket in OBS.

+

When using static website hosting, you can configure request redirection to redirect specific or all requests.

+

For more information about the application scenarios of static website hosting, see:

Configuring Static Website Hosting

+

Function

You can host static website resources such as HTML web pages, flash files, or audio and video files in an OBS bucket, so that you can provide these hosted resources using the bucket's website endpoint to end users. Typical use cases include:

+
  • Redirecting all requests to another website
  • Redirecting specific requests to another website
+

This API configures static website hosting for a bucket.

+
+

Restrictions

  • Periods (.) should be avoided in the target bucket name, or there may be certificate verification failures on the client when you use HTTPS for access.
  • The request body of the website configuration cannot exceed 10 KB.
  • To configure static website hosting for a bucket, you must be the bucket owner or have the required permission (obs:bucket:PutBucketWebsite in IAM or PutBucketWebsite in a bucket policy).
+
+

Overview

+

Tags are used to identify and classify OBS buckets.

+

If you add tags to a bucket, SDRs generated for the requests sent to this bucket will include these tags, so you can use the tags to classify SDRs for detailed cost analysis.

+

For example, if you have an application that uploads its running data to a bucket, you can tag the bucket with the application name.

+

In this manner, the costs of the application can be analyzed using tags in SDRs.

+

For details about the application scenarios of bucket tags, see:

Configuring Tags for a Bucket

+

Function

If you add tags to a bucket, SDRs generated for the requests sent to this bucket will include these tags, so you can use the tags to classify SDRs for detailed cost analysis. For example, if you have an application that uploads its running data to a bucket, you can tag the bucket with the application name. In this manner, the costs of the application can be analyzed using tags in SDRs.

+

This API adds tags to a bucket.

+
+

Restrictions

  • A bucket can have a maximum of 10 tags.
  • To configure tags for a bucket, you must be the bucket owner or have the required permission (obs:bucket:PutBucketTagging in IAM or PutBucketTagging in a bucket policy).
+
+

Method

obsClient.setBucketTagging(final SetBucketTaggingRequest request)

Overview

+

OBS provides server-side encryption for objects, so that they will be encrypted or decrypted when you upload them to or download them from a bucket.

+

The encryption and decryption happen on the server side.

+

There are different encryption methods for you to choose from.

+

With SSE-KMS, OBS uses the keys provided by Key Management Service (KMS) for server-side encryption. You can create custom keys for SSE-KMS encryption.

+

With SSE-C, OBS uses the keys and MD5 values of the keys provided by customers for server-side encryption.

+

When server-side encryption is used, the returned ETag value is not the object's MD5 value. OBS will verify the object's MD5 value as long as the upload request includes the Content-MD5 header, no matter whether server-side encryption is used or not.

+

When server-side encryption is used, you are advised to use HTTPS to transmit and receive data.

Log Analysis

+

How To Enable Logging

  1. Save the log4j2.xml file obtained from the OBS Java SDK package to the classpath root directory.
  2. Call Log4j2Configurator.setLogConfig to specify the save path of log4j2.xml directly.
+

You can obtain the default log configuration file log4j2.xml from the OBS Java SDK package, and then modify to customize the file.

+
+
+

Log Path

The log path of OBS Java SDK is specified in log4j2.xml. Logs are saved in the path represented by system variable user.dir of JDK by default. In general, there are three logs files as follows:

+ +
+ + + + + + + + + + + + + +

File Name

+

Description

+

OBS-SDK.interface_north.log

+

Northbound log file, which saves the logs about the communication between OBS Java SDK and third-party applications of users.

+

OBS-SDK.interface_south.log

+

Southbound log file, which saves the logs about the communication between OBS Java SDK and the OBS server.

+

OBS-SDK.access.log

+

Run log file of the OBS server.

+
+
+
+

Log Format

The SDK log format is: Log time|Thread number|Log level|Log content. The following are example logs:

+
#Southbound logs
+2017-08-21 17:40:07 133|main|INFO |HttpClient cost 157 ms to apply http request

+2017-08-21 17:40:07 137|main|INFO |ObsClient [setObjectAcl] cost 312 ms
+
+

Log Level

When current logs cannot be used to troubleshoot system faults, you can change the log level to obtain more information. You can obtain the most information in TRACE logs and the least information in ERROR logs.

+

Log level description:

+
  • OFF: Close level. If this level is set, logging will be disabled.
  • TRACE: Trace level. If this level is set, all log information will be printed. This level is not recommended.
  • DEBUG: Debugging level. If this level is set, information about logs of the INFO level and above, HTTP/HTTPS request and response headers, and StringToSign information calculated by authentication algorithm will be printed.
  • INFO: Information level. If this level is set, information about logs of the WARN level and above, time consumed for each HTTP/HTTPS request, and time consumed for calling the ObsClient API will be printed.
  • WARN: Warning level. If this level is set, information about logs of the ERROR level and above, as well as information about some critical events (for example, the number of retry attempts exceeds the upper limit) will be printed.
  • ERROR: Error level. If this level is set, only error information will be printed.
+
+

How to Set

The following sample code shows how to set different levels for the southbound logs, northbound logs, and OBS server run logs. (For details about log configuration, see configuration file log4j2.xml.)

SDK Exceptions

+

SDK custom exceptions (ObsException), thrown by ObsClient, are inherited from class java.lang.RuntimeException. Exceptions are usually OBS server errors, including OBS error codes and error information. This facilitates users to locate problems and troubleshot faults.

+

ObsException contains the following error information:

+
  • ObsException.getResponseCode(): HTTP status code
  • ObsException.getErrorCode(): Error code returned by the OBS server
  • ObsException.getErrorMessage(): Error description returned by the OBS server
  • ObsException.getErrorRequestId(): Request ID returned by the OBS server
  • ObsException.getErrorHostId(): Requested server ID
  • ObsException.getResponseHeaders(): HTTP response headers
  • ObsException.printStackTrace(): Prints the detailed stack trace of an exception.

What Is the Retry Mechanism of SDK?

+

SDK uses the maxErrorRetry parameter configured in Creating and Configuring an OBS Client to retry. The default value for retry times is 3. 0 to 5 is recommended.

+

If the network connection is abnormal or the server returns the 5XX error when an ObsClient API is called, the SDK performs an exponential backoff retry.

+
  • For ObsClient.putObject, when the data source is an InputStream other than FileInputStream, the SDK does not retry when an I/O exception occurs because the data stream cannot be re-read. The upper-layer application needs to retry.
  • When ObsClient.getObject is successfully called and ObsObject is returned, the SDK does not retry when an I/O exception occurs during data reading from ObsObject.getObjectContent because this situation is beyond the scope of the processing logic of the SDK. The upper-layer application needs to retry.

How to Improve the Speed of Uploading Large Files over the Public Network?

+

If a file exceeds 100 MB, you are advised to upload the file using multipart upload.

+

Multipart upload refers to splitting an object into multiple parts and uploading them separately. Each part is a contiguous portion of the object's data. You can upload parts in any sequence. A part can be reloaded after an upload failure, without affecting other parts. Uploading multiple parts of an object using multiple threads concurrently can greatly improve the transmission efficiency.

How Can I Perform a Multipart Upload?

+

In a multipart upload, you can specify a part of the file to be uploaded by performing the following steps:

+
  1. Initialize an instance of ObsClient based on the AK, SK, and endpoint.
  2. Specify the bucket name and object name to initialize InitiateMultipartUploadRequest. Call InitiateMultipartUploadRequest.setMetadata to specify the metadata of the object to be uploaded. Then, call ObsClient.initiateMultipartUpload to initiate a multipart upload task. A globally unique identifier (upload ID) for this task will be returned.
  3. Specify the bucket name and object name to initialize UploadPartRequest. Call UploadPartRequest.setUploadId to specify the upload ID to which the part to be uploaded corresponds. Call setPartNumber to specify the part number of the part. Call setFile to specify the large file to which the part belongs. Call setPartSize to specify the part size. Then, call ObsClient.uploadPart to upload the part. The ETag value of the uploaded part is returned.
  4. After all parts are uploaded, specify the bucket name, object name, uploadId, and partEtags to initialize a CompleteMultipartUploadRequest request. Then, call ObsClient.completeMultipartUpload to assemble parts.

How Do I Download an Encrypted Object Using a URL?

+

If the object is encrypted with SSE-KMS, the server automatically decrypts the object when you use the URL of the object to download it.

+

If the object is encrypted with SSE-C, you cannot access the object directly through a web browser because a request header is required for decryption. If you use code to download the encrypted object, configure the header by referring to Code Example: Downloading an Object Encrypted Using SSE-C.

+

Accessing a server-side encrypted object requires the HTTPS protocol.

Does the SDK Support Uploading, Downloading, or Copying Objects in a Batch?

+

No.

+

Currently, the SDK does not provide such APIs. You need to encapsulate the service codes for uploading, downloading, or copying objects in a batch by yourself. The procedure is as follows:

+
  1. List all objects to be uploaded, downloaded, or copied. For details about how to list objects to be downloaded, see Listing Objects.
  2. Call the API for uploading, downloading, or copying a single object for the listed objects.
+

What Is Content-Type (MIME)?

+

Multipurpose Internet Mail Extensions (MIME) type is a standard way of describing a data type. The MIME type is passed in the Content-Type header.

+

If you do not specify Content-Type when uploading an object, the SDK determines the object type based on the suffix of the specified object name and automatically assigns a value to Content-Type.

+
+

Content-Type

Content-Type indicates the type of data to send or receive and determine the form and encoding method browsers will use to display data (mainly custom client files or media files). If no content type is specified, the type will be generated based on the file name extension. If there is no extension, the content type is application/octet-stream by default.

+
+

Common Content Types

The commonly used content types are given in the table below.

Overview

+

Client-side encryption is a process where data is encrypted using the selected encryption method and information on your local PC before it is transmitted to an OBS server. During this process, the encryption method used and necessary information required for decryption will be stored in object metadata. During a download, the OBS SDK decrypts the data based on the key provided and the information stored in object metadata, and then returns the decrypted data.

+
  • OBS does not store your master key in any way. Keep your master key correct and intact. If your master key is lost or mistakenly used, your data cannot be decrypted.
  • Do not modify the decryption information stored in object metadata when moving or replicating an encrypted object or modifying the object metadata. If you do so, your data cannot be decrypted.
  • For security purposes, later SDK versions will use RSA/ECB/OAEPWITHSHA-256ANDMGF1PADDING in place of RSA for encryption and, therefore, will be incompatible with earlier versions.
  • You are advised to add the SDK version information to master-key-info to avoid data encryption or decryption failures caused by changes of encryption algorithms and key length restrictions.
  • Consider both security and performance when determining the RSA key size. Later SDK versions will require the key size be larger than 3,072 bits.
  • Consider both security and performance when configuring secureRandom.
  • RSA keys in PKCS #8 format are recommended.
+
+

Encryption Process and Cipher Suites

The OBS SDK for Java offers two cipher suite generators: CTRCipherGenerator based on AES-CTR, and CtrRSACipherGenerator based on RSA and AES-CTR.

+

If CTRCipherGenerator is used to upload objects, you need to provide a data key. The SDK then randomly generates an initial value for each object and uses the data key and initial value to encrypt the object. After the encryption, the SDK uploads the encrypted object to OBS and stores its initial value in object metadata. To download this object, you need to use the same data key used for upload. The SDK automatically obtains the initial value from object metadata, uses the data key provided and initial value to decrypt the object, and returns the decrypted data. If a different data key is provided for download, the SDK returns an unavailable decrypted file.

+

If CtrRSACipherGenerator is used to upload objects, you need to provide an RSA public key. The SDK then randomly generates a data key and initial value for each object and uses them to encrypt the object. After that, the SDK uploads the encrypted object to OBS and then uses the provided RSA key to encrypt the data key. The encrypted data key and initial value are stored in the object metadata. To download this object, you need to provide the corresponding RSA private key. The SDK then automatically obtains the data key and initial value stored in the object metadata and uses the provided RSA private key to decrypt the data key. If the provided private key does not match the public key used for upload, an error will be reported. After the data key is decrypted, the SDK uses the decrypted data key and initial value to decrypt the object and returns the decrypted data.

+
+

API Changes

CryptoObsClient is inherited from ObsClient. Except the APIs listed in the following table, all other APIs of CryptoObsClient are the same as those of ObsClient.

Decryption Information in Metadata

The SDK saves the information required for decryption in the user-defined metadata of an object and does not back it up. If you modify the stored information, data cannot be decrypted. The following table describes the information required for decryption.

Client-Side Encryption APIs

+

Initializing CryptoCipher

OBS SDK for Java provides two cipher suites for you to choose from.

+

CtrRSACipherGenerator is inherited from CTRCipherGenerator but only requires you to provide an RSA public or private key to encrypt or decrypt the randomly generated data key.

+

CTRCipherGenerator requires only one data key. This key is used to encrypt all objects.

+ +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Table 1 CtrRSACipherGenerator parameters

Parameter

+

Type

+

Mandatory (Yes/No)

+

Description

+

privateKey

+

PrivateKey

+

Yes when decrypting objects (for example, getObject)

+

Explanation:

+

RSA private key.

+

Default value:

+

None

+

publicKey

+

PublicKey

+

Yes for encryption (for example, putObject)

+

Explanation:

+

RSA public key.

+

Default value:

+

None

+

masterKeyInfo

+

String

+

No

+

Explanation:

+

Key information, which is stored in the user-defined metadata of objects to help you identify keys. You need to maintain the mappings between keys and masterKeyInfo on your own.

+

Default value:

+

None

+

secureRandom

+

SecureRandom

+

Yes

+

Explanation:

+

Secure random number generator, which is used to randomly generate cryptoKeyBytes and cryptoIvBytes.

+

Default value:

+

None

+

needSha256

+

boolean

+

No

+

Explanation:

+

Whether to verify the SHA-256 value of the encrypted data and to add SHA-256 values calculated before and after the encryption to the user-defined metadata.

+
NOTE:

To reduce memory overheads, the SDK uses streaming computing, which means that a file needs to be read and encrypted twice in a common upload and three times in a resumable upload.

+
+

Value range:

+

If need_sha256 is set to true, the SDK automatically calculates SHA-256 before and after the object is encrypted and saves the two values to the user-defined metadata of the object. In addition, the SDK adds the SHA-256 value of the encrypted object to the request header when sending a request to the server. After receiving the request, the server calculates the SHA-256 value of the object and checks the consistency between the calculated and the received values. If they are inconsistent, an error message is returned.

+

false: The SHA-256 value of the encrypted data is not verified.

+

Default value:

+

false

+
+
+ +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

How Do I Get My Account ID and User ID?

+

Obtaining the Account ID and User ID

When calling APIs, you may need to specify the account ID (DomainID) and user ID (UserID) in some requests. You need to obtain them from the console in advance. To obtain them from the console, do as follows:

+
  1. Log in to the management console.
  2. Hover the mouse pointer over the username and choose My Credentials from the drop-down list.

    On the My Credentials page, view the account ID and user ID.
